I just got a new Barber DD and it certainly is a fine pedal. I particularly like the versatility that the trimpots and the pull harmonics add. That said, I find the pedal to be a little constricted by its midrange voicing and especially by its excess compression even at lower gain levels. What mods will make the DD sound more open w/ less compression? Would switching to a TL072/082 or a Burr Brown chip help. What about adding or clipping a diode for asymmetrical clipping? Keep in mind I'm not looking for less gain (although I'll compromise if I can get the tone and feel I'm looking for) just a more dynamic feel and less congestion in the mids.
